DETAILED DESCRIPTION

One or more embodiments of the present invention provide systems and methods for controlling locks to thereby manage the plugging-in and unplugging of various types of cables and inserts into and from computing and other types of resources.

In modern cloud service providers and data centers, large numbers of computers and other similar components are housed in large facilities. Within those facilities, various cables are connected to each of the computers to allow for the computers to receive power and to communicate various types of data with each other and with external devices. The connections of each of these and other cables to the computers need to be frequently inspected and sometimes serviced, repaired or replaced. This is time consuming and can result in malfunctions in an event one or more connections are handled incorrectly or at inappropriate times. As such, management of the connections of the cables and the other cables to each of the computers in modern cloud service providers and data centers is highly important for insuring that the computers are operated properly and without failures.

One or more embodiments of the present invention provide systems and methods for management of the connections to each of the computers in modern cloud service providers and data centers or other similar securable components. This insures that the computers and the other similar securable components are operated properly and without failures.

Turning now to FIG. 1, a system 101 is generally shown in accordance with one or more embodiments of the present invention. The system 101 includes one or more computing or securable resources (hereinafter referred to as “computing resources”) 110. The system 101 could be provided as a cloud service, a shared data center, etc. in any case, each computing resource 110 can be provided as a safe 111, a server 112 that is housed in a rack 113 or another similar feature. The safe 111 can be controlled and monitored through software based mitigation systems. All requests to access the resources within the safe 111 would need to be registered and authenticated before the attempt would be approved or denied. If a user wished to unlock the safe 111, they would need to pass proper identification, such as a finger print, PIN code, etc., to a controller which would then evaluate the information and open the lock should the user possess the correct authority.

As shown in FIG. 1, the computing resources 110 can be, but are not required to be, arranged in rows and columns across one or more floors 114. In each row or column, each of the computing resources 110 can be coupled to one or more cables 115. The cables 115 can include, but are not limited to, communication cables and power cables and can carry various signals, such as power signals, data signals, etc.

With reference to FIG. 2, each of the computing resources 110 can include a set of drawers 201 where each drawer 201 can include a service processor (SP) 202 and one or more central processors (CPs) 203 that are communicative with the SP 202. Each SP 202 of each drawer 201 can be interconnected with the SPs 202 of the other drawers 201 and each CP 203 of each drawer 201 can be communicative with memory units and can form a logical cluster alone or in combination with other CPs 203.

With continued reference to FIG. 2 and with additional reference to FIG. 3, one or more of the drawers 201 of each computing resource 110 can include one or more ports 301, storage devices 302 and communications, memory or peripheral cards 303. The ports 301 can provide direct or indirect access to the storage devices 302 and the communications, memory and peripheral cards 303. Each of the ports 301 can be provided as a plug receiver 310 that a plug 320 of a cable 321 can be plugged into. The cable 321 can be provided as one or more of a power cable, an Ethernet cable, a fiber optic cable, a telecommunications cable, etc., such that the cable 321 can effectively be plugged into the computing resource 110.

With reference to FIGS. 4 and 5, a computing resource 110 as described above can include a housing 116 that is formed to define an aperture 117 and the system 101 of FIG. 1 can further include, for each cable 321 and each computing resource 110, a locking element 401. Here, each cable 321 can include the plug 320, a connector body 3201 and a receiving feature 3202. The connector body 3201 can extend outwardly and laterally from the plug 320 and the receiving feature 3202 can extend forwardly from the connector body 3201. With this or a similar construction, when the plug 320 is inserted into the plug receiver 310, the receiving feature 3202 is correspondingly inserted into the housing 116 through the aperture 117. In accordance with embodiments of the present invention, the receiving feature 3202 can be formed as an elongate element with a notch 3203 (see FIG. 6) at a distal end thereof.

With continued reference to FIGS. 4 and 5 and with additional reference to FIG. 6, the locking element 401 includes a locking feature 410 and an actuator 420. The locking feature 410 is configured to assume a locked condition or an unlocked condition. In the locked condition, the locking feature 410 engages with the notch 3203 of the plug 320 of the cable 321 such that the cable 321 is locked to the computing resource 110 and cannot be unplugged. Alternatively, in the locked condition, the locking feature 410 blocks passage of the receiving feature 3202 through the aperture 117 such that the locking feature 410 effectively prevents the plug 320 of the cable 321 from being inserted into the plug receiver 310 of the computing resource 110. In the unlocked condition, the locking feature 410 disengages from the notch 3203 of the plug 320 of the cable 321 such that the cable 321 is unlocked from the computing resource 110 and can be unplugged. Alternatively, in the unlocked condition, the locking feature 410 permits passage of the receiving feature 3202 through the aperture 117 such that the locking feature 410 effectively permits the plug 320 of the cable 321 to be inserted into the plug receiver 310 of the computing resource 110.

The actuator 420 is coupled to the locking feature 410 and is configured to control the locking feature 410 to assume the one of the locked and unlocked conditions. In accordance with embodiments of the present invention, the actuator 420 can be provided as a linear actuator or as a rotary actuator 4201 as shown in FIG. 6. In the case of the actuator 420 being provided as the rotary actuator 4201, the rotary actuator 4201 can include an output shaft 610 and a physical locking feature 620. The physical locking feature 620 is coupled to the output shaft 610 and includes one or more of a latch 621 that is configured for engagement with the receiving feature 3202 of the cable 321 (to either lock the cable 321 in place or to prevent insertion of the cable 321) and a pin configured for insertion into the receiving feature 3202. In the former case, the rotary actuator 4201 is configured to rotate the output shaft 610 in first and second opposite directions whereby the latch 621 is rotationally moved into or out of locking and unlocking positions with respect to the notch 3203.

As shown in FIGS. 4 and 5, the locking feature 410 and the actuator 420 can be disposed within an interior of the housing 116. It is to be understood, however, that this is not required and that embodiments exist in which at least one of the locking feature 410 and the actuator 420 are disposed at an exterior of the housing 116 (see FIGS. 15 and 16 and accompanying text below). Where the actuator 420 is disposed within the interior of the housing 116, the actuator 420 can be disposed on a printed circuit board (PCB) 421. This PCB 421 can include various processing elements and can generate commands for operating the actuator 420 whereby the actuator 420 is receptive of commands from the PCB 421.

With continued reference to FIG. 6 and with reference back to FIGS. 2 and 3, one or more of the SP 202 and one or more of the CPs 203 of each drawer 201 of each computing resource 110 can be configured to cooperatively define or act as a controller 630. The controller 630 can be embodied as a generic hardware management console (HMC) 631, a generic service element (SE) 632 or as another suitable form. In any case, the controller 630 can be configured to define rules for users of the system 101 (see FIG. 1) where the rules are associated with respective IDs of each of the users and established criteria associated with each user for operating the locking elements 401. The rules can, for example, set forth times when one or more of the users of the system 101 are authorized to manipulate (i.e., unplug or plug in) one or more cables 321 relative to one or more computing resources 110. Thus, the controller 630 can cause locking features 410 of corresponding locking elements 401 to assume the unlocked conditions during those times. That is, the controller 630 effectively causes the locking feature 410 of each of the locking elements 401 to assume one of the locked and unlocked conditions in accordance with respective IDs of users and the criteria established for each user.

In accordance with embodiments of the present invention, the computing resource 110 can be provided as a server in which various systems management operations are executed via the HMC 631 and the SE 632. An example of such systems management operations is configuration management. This relates to techniques, resources and tools used to initialize, configure, customize and maintain hardware, including the input/output (I/O) resources (network, storage, etc.). Both the HMC 631 and the SE 632 can be configured with user management interfaces for a first set of users defined to the HMC 631 and a second set of user defined to the SE 632. The first and second sets of users have associated privilege levels that define what operations (or tasks) they are permitted to do with respect to the computing resource.

With reference to FIG. 7, a method of operating a locking assembly of a computing resource, such as a computing resource 110 as described herein, is provided. The method includes operations that can be executed as an OS level or higher of the computing resource 110. As shown in FIG. 7, the method includes determining whether an operator is authorized to manipulate a cable relative to the computing resource (block 701). The method further includes commanding an actuator to cause a locking feature of a locking assembly to assume a locked condition to prevent the cable from being unplugged from or plugged into the computing resource in an event the determining indicates that the operator is unauthorized to unplug the cable from or to plug the cable into the computing resource (block 702). In addition, the method includes commanding the actuator to cause the locking feature of the locking assembly to assume the unlocked condition to permit the cable to be unplugged from or plugged into the computing resource in an event the determining indicates that the operator is authorized to unplug the cable from or to plug the cable into the computing resource (block 703).

In accordance with exemplary embodiments of the present invention, “HMC users” and “SE users” can be defined to have rules associated to their user IDs that would lock or unlock a cable based on the “cable criteria” associated with each of them. For example, an “HMC user,” admincasey, can be permitted to remove or insert cables for a certain card for a certain computing resource between certain hours of the day, Friday through Sunday. This “HMC user,” admincasey, is not permitted to remove or insert cables into other cards for the certain computing resource at any other time or day of the week. Furthermore, the “HMC user,” admincasey, is not permitted to remove or insert cables into any other physical port, in any other computing resource. Thus, when the “HMC user,” admincasey, successfully logs in to the HMC 631 on Saturday at 4 AM, he or she will be able to successfully issue a cable command to unlock the cable locks for which he or she is authorized. However, if the “HMC user,” admincasey, issues a cable command to unlock any other cable in any other location, the cable lock will not unlock because he or she is not permitted to unlock or lock those cables. Similar schemes can be used for the SE users.

Modern software systems often rely heavily upon various authentication methods to mitigate security risks and data integrity issues. Traditional embodiments of this concept exist strictly within the software domain protecting assets such as account numbers, passwords and other sensitive information. To gain access to these assets, there are a wide variety of techniques such as PINs, passwords, encryption and biometrics. Existing implementations, such as accessing a locked mobile device, will pass identification information through to the underlying OS or security product to authenticate the user to the desired resource.

With reference to FIG. 8, a system 801 is provided and can include one or more securable resources 810, such as computing resources or a safes or some other similar elements, locking elements 820 similar to the locking element 401 described above and a controller 830 similar to the controller 630 described above. The controller 830 is receptive of an instruction 831 to authorize users to unlock one or more of the one or more securable resources 810. The controller 830 is further configured to perform OS level authentication of the users and OS level control of the one or more locking elements 401 in accordance with the instruction 831 to authorize users and the OS level authentication.

As shown in FIG. 8, the instruction 831 is received from an external communication and can be received via one or more of an access control system or service (ACSS) interface 832 and a change mode (CHMOD) interface 833. The instruction 810 can be one of time sensitive and condition dependent. The OS level authentication of the users can be performed by the controller 830 performing one or more of fingerprint and pin code OS level authentication at fingerprint and pin code verification elements 8301 and 8302. The OS level control of the one or more locking elements 82 can be performed by the controller 830 whereby the controller 830 causes the one or more locking elements 820 to assume the respective unlocked conditions in accordance with a requesting user being authorized by the instruction 831 to authorize users and being authenticated by the OS level authentication by the controller 830.

An example of the system 801 of FIG. 8 can be seen in a physical lock on a safe which is controlled and monitored through software based mitigation systems as noted above. All requests to access the resources within the safe would need to be registered and authenticated before the attempt would be approved or denied. If a user wished to unlock the safe, they would need to pass proper identification, such as a finger print, PIN code, etc., to the controlling OS which would then evaluate the information and open the lock should the user possess the correct authority. This notion can be extrapolated to other physical resources as well including input/output (I/O) ports, storage devices and communication cards. An employee in a company may be granted temporary authority to add or remove devices. This authority can be time sensitive to limit access to only during the employee's shift or during emergencies such as a system outage or other critical situation. An administrator or other authorized user would be required to authorize these users via standard interfaces in the controlling operating system such as ACSS or CHMOD. Having additional physical information protection will prevent and mitigate unauthorized access from malicious users and disgruntled employees trying to cause physical harm to a set of resources or attempting to steal information.

With reference to FIG. 9, a method of operating a system, such as the system 801 of FIG. 8, is provided. As shown in FIG. 9, the method includes controlling locking elements to assume locked conditions whereby corresponding securable resources are locked by the locking elements (block 901), receiving an instruction to authorize users to unlock one or more of the securable resources (block 902) and receiving a request from a user to unlock and thereby gain access to one or more of the securable resources (block 903). The method further includes determining whether the user is authorized to unlock and thereby gain access to the one or more of the securable resources associated with the request (block 904), performing operating system (OS) level authentication of the user (block 905) and performing OS level control of the corresponding locking elements in accordance with the user being determined to be authorized and authenticated (block 906).

As demand for content and services continues to grow, more machines and resources are utilized in data centers and other computing centers. A common problem in these areas is having machines fail and necessitate that a replacement be installed and configured quickly to maintain availability to the end customer. As machines are added and removed to a large network of devices working in unison, wires and cables are needed to enable proper communications. During maintenance and updates to these machines, sometimes the incorrect wire is removed or one is added to an incorrect port causing outages, delays and other damages.

Thus, with reference to FIG. 10, the system 801 of FIG. 8 can be expanded to include one or more resources, such as safes 1001 and computing resources 1002, where each of the one or more resources includes multiple independently securable resources, such as separate interiors 1003 of the safe 1001 and one or more of power and data communication cables which are insertable into ports, storage devices or communications cards 1004 of the computing resource 1002. In accordance with embodiments of the present invention, the instruction 831 (see FIG. 8) for the safe 1001 can relate to the locks of one or more but not necessarily all of the separate interiors 1003 and the instruction 831 (see FIG. 8) for the computing resource 1002 can similarly relate to one or more but not necessarily all of the various components of the computing resource 1002. In the cases of the resources of FIG. 10, the system 801 of FIG. 8 operates substantially similarly as described above.

In accordance with exemplary embodiments of the present invention, a physical access port on a securable resource can be guarded by physical locks and risk mitigation systems that can only be removed through the authorization of a software based system such as ACSS or CHMOD. A use case may be that a communication cable needs to be replaced between a server and communications router. A system administrator may authorize a specific user to remove a specific cable by unlocking only the required port on the server. This will prevent accidental or malicious disconnects from healthy communications on the server as physical locks or pins will restrict access to other resources and devices interfacing with the desired server. The result is an increase in reliability and security for devices operating within a test floor or data center where configurations are constantly changing and maintenance is always ongoing.

With increasing requirements for computing power and data storage, cloud providers are relying more and more on data centers that include a variety of tools and machines. Each unique tool or device usually requires a skilled technician or employee to manage and configure it for optimal use so customers receive reliable and secure services. A multitude of security measures are often implemented to prevent unauthorized access to sensitive resources. Each resource often has unique protections in place that users must authenticate against in order to manage the system. This generally leads to redundant authentication steps and lost time as an authorized employee must start the process over from scratch as they jump between systems to perform required maintenance.

With reference to FIG. 11, a common interface 1101 can be provided for use with the controller 630 or the controller 830 described above as well as additional controllers 1102, which are separate and independent from the controller 630 or 830 and one another. The controller 630 or 830 and the additional controllers 1102 are tied to the common interface 1101 and the common interface 1101 is configured to authenticate the users. To this end, the common interface 1101 can be embodied in a hypervisor or a multiplexer and can include one or more of a graphical user interface (GUI) 1110 and a physical authentication interface 1120 that, in turn, can include one or more of an RFID badge authentication interface 1121 and a fingerprint identification device 1122. In these or other cases, the controller 630 or 830 is configured to perform OS level control of locking elements in accordance with at least an authentication of the users by the common interface 1101.

With reference to FIG. 12, a method of operating a system, such as system 101 of FIG. 1 or system 801 of FIG. 8 is provided. As shown in FIG. 12, the method includes controlling locking elements to assume locked conditions whereby corresponding securable resources are locked by the locking elements (block 1201), receiving an instruction to authorize users to unlock one or more of the securable resources (block 1202), receiving a request from a user to unlock and thereby gain access to one or more of the securable resources (block 1203) and determining whether the user is authorized to unlock and thereby gain access to the one or more of the securable resources associated with the request (block 1204). In addition, the method includes receiving an indication of authentication of the user from a common interface (block 1205) and performing OS level control of the corresponding locking elements in accordance with the user being determined to be authorized and the indication of the authentication of the user being received (block 1206).

The OS level authentication provided by to the common interface 1101 allows an authorized user to authenticate once to gain access to all necessary resources. This will, for example, allow a system administrator to perform maintenance on cables or communication devices that interface across multiple systems within the data center. If an unauthorized or disgruntled employee attempts to access resources, physical locks and security devices will prevent them from removing or altering cables and connections across these sensitive resources. Only authorized users will be allowed to rewire and maintain devices within the data center at the discretion of a system administrator.

Many devices are now incorporating hardware based authentication schemes to minimize vulnerabilities and security risks while accessing certain resources. Most modern mobile devices, for example, employ biometrics such as a finger print scanner or facial recognition software to authenticate specific users to the contents of the device. These metrics generally tend to interface with a security product to grant or deny access to specific software resources such as bank account information and other sensitive data. Many physical assets may also be protected by biometrics or other physical protections such as RFID badging. These systems tend to work off of standalone or proprietary validation systems which often times have delayed responses or simple work arounds such as tailgating through a badge locked door.

With reference to FIG. 13, a physical authentication interface 1301 can be provided for use with the controller 630 or the controller 830 described above. In these or other cases, the physical authentication interface 1301 can be configured to enable or disable a capability of the controller 630 or 830 to perform the OS level authentication. In accordance with embodiments of the present invention, the physical authentication interface 1301 can include one or more of an RFID badge authentication interface 1310 and biometrics, such as a fingerprint identification device 1320.

With reference to FIG. 14, a method of operating a system, such as system 101 of FIG. 1 or system 801 of FIG. 8 is provided. As shown in FIG. 14, the includes controlling locking elements to assume locked conditions whereby corresponding securable resources are locked by the locking elements (block 1401), receiving an instruction to authorize users to unlock one or more of the securable resources (block 1402), receiving a request from a user to unlock and thereby gain access to one or more of the securable resources (block 1403) and determining whether the user is authorized to unlock and thereby gain access to the one or more of the securable resources associated with the request (block 1404). In addition, the method includes determining whether OS level authentication capability is enabled or disabled by, for example, receiving an indication thereof from a physical authentication interface (block 1405), performing the OS level authentication of the user in an event the OS level authentication capability is enabled (block 1406) and performing OS level control of the corresponding locking elements in accordance with the user being determined to be authorized and authenticated (block 1407).

With reference to FIGS. 15 and 16 and, in accordance with embodiments of the present invention, at least one of the locking feature 410 and the actuator 420 can be disposed at an exterior of the housing 116. Here, again, each cable 321 can include the plug 320, the connector body 3201 and the receiving feature 3202. The connector body 3201 can extend outwardly and laterally from the plug 320 and the receiving feature 3202 can be formed as a pocket 3204. With this or a similar construction, when the plug 320 is inserted into the plug receiver 310, the receiving feature 3202 is disposed adjacent to an exterior facing surface of the housing 116. The locking feature 410 is configured to assume a locked condition or an unlocked condition. In the locked condition, the locking feature 410 engages with the pocket 3204 such that the cable 321 is locked to the computing resource 110 and cannot be unplugged (see FIG. 15). Alternatively, in the locked condition, the locking feature 410 blocks passage of the receiving feature 3202 such that the locking feature 410 effectively prevents the plug 320 from being inserted into the plug receiver 310. In the unlocked condition, the locking feature 410 disengages from the pocket 3204 such that the cable 321 is unlocked from the computing resource 110 and can be unplugged (see FIG. 16). Alternatively, in the unlocked condition, the locking feature 410 permits passage of the receiving feature 3202 such that the locking feature 410 effectively permits the plug 320 to be inserted into the plug receiver 310.

The actuator 420 is coupled to the locking feature 410 and is configured to control the locking feature 410 to assume the one of the locked and unlocked conditions. In accordance with embodiments of the present invention, the actuator 420 can be provided as a linear actuator or as a rotary actuator 4201 as shown in FIGS. 15 and 16. In the case of the actuator 420 being provided as the rotary actuator 4201, the rotary actuator 4201 can include an output shaft 610 that extends to an exterior of the housing 116 and a physical locking feature 620. The physical locking feature 610 is coupled to the output shaft 610 at the exterior of the housing 116 and is configured for engagement with the receiving feature 3202 of the cable 321 (to either lock the cable 321 in place or to prevent insertion of the cable 321). The rotary actuator 4201 is configured to rotate the output shaft 610 in first and second opposite directions to be rotationally moved into or out of locking and unlocking positions with respect to the pocket 3204.

Various embodiments of the invention are described herein with reference to the related drawings. Alternative embodiments of the invention can be devised without departing from the scope of this invention. Various connections and positional relationships (e.g., over, below, adjacent, etc.) are set forth between elements in the following description and in the drawings. These connections and/or positional relationships, unless specified otherwise, can be direct or indirect, and the present invention is not intended to be limiting in this respect.
